Former White House strategist Karl Rove appeared on “Hannity” Wednesday to defend himself and his super PAC American Crossroads against critics who charge that he is seeking out and potentially exerting improper influence on the Republican Party.

Earlier this week, an email was distributed on behalf of the activist group Tea Party Patriots with a photo depicting Rove as a Nazi. The group later apologized, but Rove questioned why the incident received so much more media attention than Bob Woodward’s suggestion on “Fox News Sunday” over the weekend that Rove has set himself “up as a kind of politburo.”
